You can get workbooks through Amazon.. try this link.
http://www.amazon.com/s/ref=nb_sb_ss_c_ ... aps%2C1012 If it doesn't work just search dialectical behavior therapy. I also suggest reading the reviews... Also search youtube. I know Marsha Linehan has stuff on there, and probably find tons of other stuff. There is no right or wrong, whatever works for you is what works.

there's also a website
http://www.dbtselfhelp.comWhether or not you can learn it on your own depends on well you can grasp the material. If you can afford a dbt therapist, that would be your best option. If you can't try the workbooks!
DBT overall is great. It will help in many areas, may not solve everything. There have been critical areas in my life that dbt has not helped with. It doesn't have anything to do with dbt or me not trying.. There are things that I just can't relate to in my brain (that a normal person would experience/feel), and I've had to radically accept that. Will it change in the future maybe/maybe not. That's what dbt is all about. I intend on writing something about this at some point.. I'm just to lazy at the moment, and too much $#%^ running through I'm head to put my thoughts together. Feel free to pm if you have questions.
best!
